Question

Read this excerpt from a website.

Sugar has been determined to have cognitive effects on consumers. While glucose (sugar) is essential to proper brain function, an overabundance of this nutrient can have severe consequences for brain health. High-sugar diets can impair the production of a protein needed to maintain working synapses, which are the connections between nerve cells. Without an adequate amount of this protein, communication among synapses starts to break down, resulting in cognitive decline. Medical professionals are distressed by the overwhelming amounts of added sugar in heavily consumed foods. To break the desire to indulge in sweets, one may need to seek medical guidance.
